The problem appears to be bad code generation when cc1 is compiled with
-O2. Building gcc with -O1 seems to generate a compiler that works.
The vax port has been changed to use -O1 (with a few other specific
optimizations needed to allow other parts of the vax build to work) on
HEAD. A pullup patch for the 4.0 branch is forthcoming.
